Specification of Letters Patent.

Patented July 16, 1907.

Application filed November 15,1906. Serial No. 343.625.

To all whom it may concern:

Be it known that 1, ROBERT W. PARKER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Vise, of which the following is a specification.

This invention relates to vises and has for its object to provide a vise having a foot-operated lever associated therewith whereby the clamping jaws may be operated independently of the usual adjusting screw.

further object of the invention is to provide a vise including relatively stationary and movable jaws one of which is operatively connected with the foot-lever so that by depressing said lever the opposite jaw may be clamped in engagement with the object to be operated upon.

A further object is to provide a foot-operated lever one end of which is seated in a sectional casing carried by the stationary jaw'and adjusting screw, respectively, there being links or pins interposed between the lever and the adjacent walls of the casing sections thereby to separate said sections and thus effect the movement of the pivoted jaw when the lever is depressed.

A still further object of the invention is to generally improve this class of devices so as to increase their utility, durability and efiiciency as well as to reduce the cost of manufacture.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, and illustrated in the accompanying drawings, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims. I

Figural is a perspective view of the vise constructed in accordance with my invention. Fig. 2 is a transverse sectional view. Fig. 3 is a side elevation partly in section showing the positionof the headed end of the foot-operated lever.

Similar numerals of reference indicate corresponding parts in all of the figures of the drawings.

The improved vise comprises a stock or shank 5 one end of which constitutes a stationary or fixed jaw 6 while the opposite end thereof is provided with an annular shoulder 7 adapted to support a clip or bracket 8.

Secured to and preferably formed integral with the intermediate portion of the stock 5 are laterally extending arms 9 and 10 between which is pivotally mounted on a pin or bolt 11, the shank 12 of the movable jaw 13. The movable jaw 13 is normally and yieldably supported in open or inoperative position by means of a fiat spring 14 one end of which bears links 30.

against the shank 12 while the opposite end is secured to the stock 5 by a U shaped clip or yoke 15. The oppositearms of the yoke 15 are provided with alined slots 16 for the reception of a wedge or key 17 which bears against the adjacent surface of the stock 5 and stock.

The stationary and movable jaws are connected by an adjusting screw 18 one end of which passes through an opening 19 in the movable jaw 13 while the opposite end thereof is seated in a sleeve or collar 20 carried by and movable within the stationary jaw G. The sleeve 20 is provided with an enlarged head 21 which is seated in a recess 22 formed in a casing or housing 23, said sleeve being provided with a longitudinal spline or key 24 .which engages a corresponding key-seat 25 formed in the stationary jaw 6 and thus serves to lock the sleeve 21 against rotary movement.

Seated in a recess 26 formed in the outer face of the stationary jaw 6 and rigidly secured to the latter in any suitable manner is a casing 27. 27 are provided with lateral extensions having recesses or chambers 28 formedtherein in which are seated and housed the laterally extending heads 29 of rods or The heads 29 are formed with oppositely disposed notches 0r grooves 31 for the reception of the adjacent ends of suitable pins or links 32 preferably formed of spring metal and having theiropposite ends bearing against the adjacent walls of the chambers 28 The casings 23 and serves to clamp the spring 14 in engagement withsaid so that by exerting a downward pressure on the rods 30 I 33 to afoot-operated lever 34 preferably mounted between the arms of the clip 8 and provided with a terminal foot-piece 36 for manipulation by the operator.

It will thus be seen that by rotating the handle 37 of the screw 18 the clamping jaws may be adjusted laterally into and out of engagement with the object to be operated upon. It will also be observed that by depressing the foot-lever 34 the heads 29 of the rods 30 will be forced downwardly thus exerting a lateral pressure on the pins 32 and separating the sections 23 and 27. The jaw 6 being relatively stationary, the section 27 carrying the adjacent end of the screw 18 will be forced laterally and draw or force the movable jaw 13 into engagement with the object to be operated upon thus permitting the jaws to be operated independently of the adjusting screw.

As soon as the foot-lever 34 is released the spring 14 will automatically return the movable jaw to open or inoperative position.

From the foregoing description it is thought that the construction and operation of the device will be readily understood by those skilled in the art and further description thereof is deemed unnecessary.

Having thus described the invention what is claimed is:

1. A vise including relatively stationary and movable clamping jaws, an adjusting screw extending through and connecting said jaws for moving the latter to operative and inoperative position, and means interposed between the screw and the adjacent jaw for operating the jaws independently of said screw.

2. A vise including relatively stationary and movable clamping members, a hand-operated device extending through and connecting said jaws for moving the latter to operative and inoperative position, and a foot-lever operatively connected with the hand-operated device and the adjacent jaw, respectively, for moving said jaws to operative position independently of the hand-operated device.

3. A vise including relatively stationary and movable clamping members, an adjusting screw connecting said clamping members for moving the same to operative and inoperative position, a sectional casing one section of which is carried by the adjusting screw and the opposite section by the adjacent jaw, and means interposedbetween the casing sections for operating the jaws independently of the adjusting screw.

4. A vise including relatively stationary and movable clamping jaws, an adjusting screw extending through and connecting said clamping jaws for moving the latter to operative and inoperative position, a foot-lever operatively connected with the adjusting screw and the adjacent jaw, respectfully for moving said jaws to operative position independently of the adjusting screw, and a spring for automatically returning the jaws to inoperative position.

5. A vise including relatively stationary and movable jaws, an adjusting screw for moving the jaws to operative and inoperative position, said screw being provided with a casing a rod one end of which is interposed between the casing and the adjacent jaw, links bearing against the rod, and a foot-operated lever pivotally connected with the rod for moving the clamping jaws to operative position inde pendently of the adjusting screw.

6. A vise including relatively stationary and movable clamping members, hand operated means connecting said jaws for moving the same to operative and inoperative po sition, a sectional casing, one section of which is secured to the adjusting screw and the opposite section thereof carried by the adjacent jaw, and means carried by said sections for separating the same thereby to operate the jaws independently of the hand-operated means.
